1 maintenance
Location for any kind of maintenance task. At the moment there's only pending requests to take care of. If MM, for example, would rely on a SQL database and there would be a command to optimize the database e.g. remove outdated entries, this would be the place to give that command a home.
TODO
There are also some maintenance tasks that are mixed with configuration options in the current (MM2) interface. If possible, they should find a new home here.
1.1 requests
New home for old "pending requests". This is where work on pending requests takes place. Notification of pending requests takes place in the "notification area", which is visible on every page.
2 options
Location to subsume all options that can be applied to a list.
2.1 General
2.1.1 Subscription Rules
2.1.2 Language
Which languages are offered and what is the default language of this list?
2.2 Non-Digest/Digest
Settings for list in Digest and Non-Digest mode.
2.3 Filter
This is a new umbrella that subsumes some of the former "Privacy Options", "Content filters" et al. It's place for any kind of filter, be it that it works on any envelope data, any header or body or any other filter.
2.3.1 Sender
The former "Sender Filters".
2.3.2 Recipient
The former "Recipient Filters".
2.3.3 Spam
The former "Spam Filters".
2.3.4 Message
The former "Content Filters".
2.3.5 Topics
The former "Topics".
2.4 Bounces
The former "Bounce Processing".
2.5 Archive
The former "Archiving Options"
2.6 Gateways
A place for Gateways in General. Currently this is Mail<->News Gateway settings only. If we add more Gateways, this should be the place to configure them.
2.7 Auto-Responder
The former "Auto-Responder".
2.8 Plugins
Any Plugin that configures a list behaviour (as opposed to subscriber plugins or system plugins) registers and offers its configuration options below into this section.
3. subscriptions
Shows a searchable list of all list subscribers.
Usability consideration
If, but only if (!), we don't overload this interface then we should add a dialogue to add one 
subscriber. Then we could add an option to remove a single subscriber along with each subscriber list item.
3.1 subscribe
Dialogue to add a subscriber (mass subscription).
3.2 remove
Dialogue to remove a subscriber (mass unsubscription).
4. statistics
Place for any kind of statistic module.
4.1 System
TODO: Specify new feature
Visualize system performance in tables and graphs.
4.2 List
TODO: Specify new feature
Visualize list performance in tables and graphs.
4.3 User
TODO: Specify new feature
Visualize user performance in tables and graphs e.g. ten most active users or ten users whose reply ends a thread.
5 plugins
This is the place where Mailman lists installed plugins - whether they work or not, whether they have been enabled or not.
If there's a plugin the admin should see it here.
Idea
This could also be the place to list contributed plugins and install them over the web interface.
5.1 plugin 1
This lists the plugin name, a description, it's version number, author, contact info and it's current status (works/doesn't work incl. debug message, enabled/disabled)
5.2 plugin x
Another plugin ...
